改进的经典信道消息完整性认证方法

Improved Integrity Authentication Method of Classical Channel Message

面对消息传输过程中各种各样的威胁与攻击,信息的接收方有必要对收到或保存的消息进行完整性验证,以保证消息在传输或存储过程没有被篡改或者替换。本文提供了一种具有信息论安全性、一定错误容忍及攻击容忍能力的消息完整性认证方案,将随机置换和纠错编码应用于消息完整性认证中,提高了消息认证码的安全性和容错性。

Facing all kinds of threats and attacks in the message transmission process, the recipient of the information has to verify the integrity of the received or preserved message, to ensure that the message during transmission or stor?age has not been tampered or replaced. This paper provides a message integrity authentication scheme with informa?tion theoretic security and certain fault tolerance and attack tolerance ability, random permutation and error correc?tion coding are applied in message integrity authentication to improve the security and fault tolerance of message au?thentication code.
